ACI SP-220

Autogenous deformation of concrete is the free deformation of sealed concrete at a constant temperature. A number of observed problems with early-age cracking of high-performance concrete can be attributed to this phenomenon. During the last 10 years, this has led to an increased focus on autogenous deformation within both concrete practice and concrete research.

The papers in this publication were presented at the American Concrete Institutes Fall Convention in Phoenix, Arizona, October 2002, and will help readers understand the complexity of the autogenous deformation of concrete. The 12 papers from eight different countries indicate the broad, global research efforts dealing with autogenous deformation, and illustrate that interest in autogenous deformation is shared throughout the worldwide concrete community.
